STT-18 Industrial Tug Tow Tractor

Product Id Sku:STT-18

Extremely efficient, 48V A/C electric tug tow tractor that can tow up to 25,000 lbs. Sit-down operation. Designed to be used with optional "smart charge" battery and charger systems to allow for opportunity-charging at shift changes and breaks to provide 3 shifts of operation without having to change batteries. 


At the request of a major U.S. auto manufacturer, Eagle Tugs accepted the challenge of creating an industrial tug tow tractor that would allow them to standardize their global fleet. After years of research and design, with the collaboration of ergonomic and safety engineers and continuous feedback from tug tow tractor operators world-wide, the Eagle STT was born. Eagle Tugs proudly introduces this new generation of electric tuggers that are energy-efficient, ergonomically-correct, and flexible enough to meet material handling needs across multiple manufacturing and distribution platforms.

The STT was designed to maximize reliability and reduce unproductive "down-time". With its solid steel plate construction and its vibration reducing front and rear suspension, the STT features an unsurpassed 1,000-hour Preventative Maintenance schedule. Adding to the STT's reliability is its high-efficiency A/C electric drive, which requires no preventative maintenance. When you team this with a "Smart Charge" battery and charger, the result is a material handling tool with unparalleled productivity that can streamline any operation. If batteries may be an issue for your operation, browse the rest of our tow tractors to find the right fit for you.

By choosing the Eagle STT as the standard for your entire tug tow tractor fleet, the result is reduced cost of ownership by having one set of replacement parts, fewer maintenance personnel, and reduced operator and maintenance training time.
